The appearance of the bubble refers to a shape, a color, a size, a pattern, a texture, and the like of a displayed bubble. The appearance includes at least a shape.

FIG. 14 is a diagram showing an example of a bubble having an appearance defined by a calculation formula according to at least one of the embodiments of the present disclosure.

A bubble SB01 has a circular appearance. Although the bubble SB01 is drawn in black in the drawing, the bubble SB01 can be drawn in various colors other than black in practice. In step St61, the calculation formula specifying unit 11Z can specify a calculation formula A that defines an appearance of the bubble SB01.

The calculation formula A is defined as length(p)−r. Here, p refers to a point in a two-dimensional coordinate system (an XY coordinate system in the present example). The length(p) refers to a function that outputs a distance (length) from an origin to the point p in the coordinate system. The function length(p) can be expressed by the following calculation formula in which a value of an x coordinate of the point p is p.x and a value of a y coordinate of the point p is P.Y.

length(p)=((p.x)²+(p.y)²)^(1/2)

The calculation formula A includes ‘r’ that represents a radius of a circle. The radius ‘r’ of the circle may be a fixed value. The radius r of the circle may be a number (variable) whose value changes.

The calculation formula A specified in step St61 defines an appearance of the bubble SB01. In fact, when the distance from the origin to the point p is equal to or less than r, a calculation result of the calculation formula A is a value of 0 or less. The bubble SB01 having a black circular shape is defined by drawing each point (each pixel on a displayed image) at which the calculation result of the calculation formula A is a value of 0 or less in black. In step St62, the bubble creating unit 12Z creates an image of the bubble SB01 based on the specified calculation formula A.

FIG. 15 is a diagram showing an example of a bubble having an appearance defined by a calculation formula according to at least one of the embodiments of the present disclosure.

A bubble SB02 has a rectangular appearance. Although the bubble SB02 is drawn in black in the drawing, the bubble SB02 can be drawn in various colors other than black in practice. In step St61, the calculation formula specifying unit 11Z can specify a calculation formula B that defines an appearance of the bubble SB02.

The calculation formula B is defined as max(abs(p.x)-size.x, abs(p.y)-size.y). Here, p refers to a point in a two-dimensional coordinate system (an XY coordinate system in the present example). Furthermore, p.x represents a value of an x coordinate of the point p, and p.y refers to a value of a y coordinate of the point p.

Here, a function max(a, b) outputs a larger value between a value ‘a’ and a value ‘b’. A function abs(X) outputs an absolute value of a value X. A function abs(X) can also be expressed as |X|.

Here, size.x represents a half of a length of the rectangle in an X axis direction. Furthermore, size.y represents a half of a length of the rectangle in a Y axis direction. Each of the size.x and the size.y may be a fixed value in the calculation formula B. Alternatively, each of the size.x and the size.y may be a number (variable) whose value changes.

The calculation formula B specified in step St61 defines an appearance of the bubble SB02. In fact, when the point p is a point inside the rectangle, a calculation result of the calculation formula B is a value of 0 or less. The bubble SB02 having a black rectangular shape is defined by drawing each point (each pixel on a displayed image) at which the calculation result of the calculation formula B is a value of 0 or less in black. In step St62, the bubble creating unit 12Z creates an image of the bubble SB02 based on the specified calculation formula B.

FIG. 16 is a diagram showing an example of a bubble having an appearance defined by a calculation formula according to at least one of the embodiments of the present disclosure.

FIG. 16 shows bubbles having various appearances. Detailed description of calculation formulas that define the bubbles is omitted, and bubbles having such appearances or the like can be defined by calculation formulas. An appearance of a bubble may be obtained by combining a plurality of calculation formulas. In step St61, the calculation formula specifying unit 11Z can specify various calculation formulas that define an appearance of a bubble. In step St62, the bubble creating unit 12Z creates an image of a bubble based on the specified calculation formulas.

A color, a size, a pattern, a texture, and the like of a bubble can also be defined by a calculation formula. For example, when RGB values (values of R, G, and B are 0 to 255, respectively) based on additive color mixing are used to express colors, the value of R can be expressed by a calculation formula. The pattern can be expressed by a calculation formula in a similar manner to the shape. The size can be expressed by a calculation formula as indicated by the radius r shown in FIG. 14 . Regarding the texture, for example, transparency (for example, an alpha value) of a bubble can be expressed by a calculation formula. The calculation formula specifying unit 11Z specifies calculation formulas that define colors, sizes, patterns, texture, and the like of the bubbles in addition to the shapes of the bubbles. The bubble creating unit 12Z creates images of the bubbles having the colors, the sizes, the patterns, the textures, and the like of the bubbles defined by the specified calculation formulas. The bubble creating unit 12Z can also create a bubble having any appearance as long as the appearance can be expressed by a calculation formula. Therefore, it is possible to present various kinds of performances depending on a shape, a color, and the like of a bubble.

A bubble image in the sixth embodiment is dynamically created by calculation based on a calculation formula. Therefore, the bubble image does not need to be statically stored as an asset (material) in a storage unit (a storage medium or a storage device). Therefore, the bubble image in the sixth embodiment does not compress a storage area. On the other hand, in the case of a bubble image stored in a storage unit (a storage medium or a storage device) as a static asset (material), many kinds of image data are stored. In particular, when a bubble is to be displayed as an animation, a large number of sequential images for forming the animation are stored in the storage unit (a storage medium or a storage device). Such a static asset has a large amount of data and compresses a storage area.

Here, dynamic creation of a bubble image refers to that the bubble image is not statically stored in a storage unit (a storage medium or a storage device) and is created by calculation each time. However, a part of the dynamically created bubble image may be stored in a storage unit (a storage medium or a storage device) and reused depending on a situation.

A bubble image may be created using a shader that performs shading processing in a non-limiting manner. A bubble image may be created without using a shader. A processor used for creating a bubble image may be a GPU, a CPU, or another computing device (for example, an FPGA). A bubble image may be created as a two-dimensional (2D) image, or may be created as a three-dimensional (3D) image. After a bubble image is created as a three-dimensional (3D) image, the bubble image may be projected onto a two-dimensional space to create a two-dimensional (2D) bubble image.

A bubble image in the sixth embodiment is not affected by enlargement or reduction of a display size, and image quality can be ensured. For example, in the case of the bubble SB01 in FIG. 14 , when the value of r in the calculation formula A is increased, the bubble creating unit 12Z creates a bubble having a larger circular shape. When the value of r in the calculation formula A is reduced, the bubble creating unit 12Z creates a bubble having a smaller circular shape. In the case of the bubble SB02 in FIG. 15 , when the value of size.x or size.y in the calculation formula B is increased, the bubble creating unit 12Z creates a bubble having a larger rectangular shape. When the value of size.x or size.y in the calculation formula B is reduced, the bubble creating unit 12Z creates a bubble having a smaller rectangular shape. Here, in the case of a bubble image stored in a storage area as a static asset (material), when the bubble image is enlarged to a size equal to or larger than resolution of the bubble image, image quality deteriorates.

FIG. 17 is a diagram showing examples of calculation formulas defined for creating bubbles according to at least one of the embodiments of the present disclosure.

A calculation formula may be defined in advance in a bubble creation program or in a format that can be referred from the bubble creation program. FIG. 17 shows predefined calculation formulas from a calculation formula 001 to a calculation formula 013 as non-limiting examples. The predefined calculation formulas are not limited thereto.

A “basic shape” indicates an outer shape (for example, a circular shape, a rectangular shape, an elliptical shape, or the like) of a bubble corresponding to a calculation formula. A “variable 1” and a “variable 2” indicate content of a value that can be input as a variable of a calculation formula. Although the variable 1 and the variable 2 are described for the convenience of description, the number of variables of one calculation formula is not limited to 1 or 2. The number of variables of one calculation formula may be 0 or 3 or more. A “bubble appearance change” indicates a change of an appearance of a created bubble due to a change of a value of a variable (how an appearance of a bubble changes when a value of a variable changes).

(Animation Display)

When the calculation formula specifying unit 11Z specifies a calculation formula having a variable, an appearance of a bubble created by the bubble creating unit 12Z changes in accordance with a change of a value of the variable. That is, the bubble can be displayed by animation by changing the value of the variable. The bubble to be created may be updated at regular intervals. For example, the bubble may be updated for each frame. When a frame rate (fps) is 60, the bubble is updated 60 times per second. Those skilled in the art can freely design what kind of value is used as a variable and how the appearance of a bubble is changed in accordance with the variable. Therefore, a change in an appearance of a bubble defined by a calculation formula can be diversified.

When a bubble image is statically stored as an asset (material) in a storage unit (a storage medium or a storage device), there is a method in which affine transformation (rotation, enlargement or reduction, and movement) is performed on one static image that is the bubble image, and the static image is displayed by animation. In the case of this method, an essential shape of the bubble image does not change, and it is difficult to present various expressions. On the other hand, when an appearance of a bubble is defined by a calculation formula, various changes can be made to the bubble image by changing a value of a variable, an expression is diversified, and a range of the expression is increased.

FIG. 18 is a diagram showing a change of a bubble corresponding to a variable according to at least one of the embodiments of the present disclosure.

The calculation formula specifying unit 11Z specifies one or more calculation formulas based on a numerical value indicating content of a line combined with a bubble. Here, the term “line combined with a bubble” refers to a line that is displayed in a manner of overlapping a frame image when the frame image of the bubble is displayed on a game screen or the like.

(Digitization of Emotion of Speaker Expressed by Line)

Content of a line may represent an emotion of a speaker in a non-limiting manner. For example, the calculation formula specifying unit 11Z specifies a calculation formula having a variable indicating an anger degree (anger level) expressed by a line. For example, when content of a line is “Autumn is cool and good”, an anger level is 0. For example, when content of a line is “Don't be silly!!”, an anger level is 3. The calculation formula specifying unit 11Z specifies the calculation formula 003 and the calculation formula 008 having a variable 1 indicating an “anger level (normal 0 to rage 10) based on content of a line” with reference to FIG. 17 . FIG. 18 shows a bubble SB03A that has an appearance of a bubble created by the bubble creating unit 12Z when an anger level is 0. A bubble SB03B has an appearance of a bubble created by the bubble creating unit 12Z when an anger level is 6. An anger level of a speaker is indicated by a size of thorns provided at a bubble frame. Although the bubble is drawn in black in FIG. 18 , the bubble SB03B is actually more reddish than the bubble SB03A (the calculation formula 008).

The calculation formula specifying unit 11Z may determine a value of an anger level based on content of a line according to various algorithms. For example, a storage unit (a storage medium or a storage device) of the server 10 stores in advance a correspondence table in which specific texts such as “Don't be silly”, “Damn it”, and “!” and a value of an anger level (an absolute value or an addition value) when such texts are included in a line are associated with each other. The calculation formula specifying unit 11Z calculates a value of an anger level based on the texts included in a line with reference to the correspondence table. The server 10 may include a learning model of machine learning. The learning model may be, for example, a learned model obtained by machine learning texts included in a line when the texts included in a line are input and a value of an anger level is output. The calculation formula specifying unit 11Z inputs the texts included in the line to the learned model, and calculates the value of the anger level. An anger level calculation algorithm is not limited to the one described above, and a person skilled in the art may appropriately determine a calculation algorithm. The calculation formula specifying unit 11Z may calculate a value of an anger level based on the texts included in the line by using any method that can be implemented by a person skilled in the art.

Content of a line combined with a bubble is not limited to an anger level. For example, the calculation formula specifying unit 11Z may determine various values such as an affection level, a tsundere level (hot and cold level), a dislike level, a curiosity level, a kindness level, a malice level, a sincerity level, a surprise level, a sadness level, and a superiority level, which are expressed by a line, based on texts included in the line. Then, the calculation formula specifying unit 11Z specifies a calculation formula having variables of these values.

(Digitization of Impression Given to Receiver Based on Line)

Content of a line may refer to an impression given to a person (a user, a viewer, a game player, and the like) who receives an utterance related to the line in a non-limiting manner. The impression is an emotion to a speaker possessed by a person (receiver) who received the utterance related to the line. For example, the receiver has an impression on the speaker, such as “this utterance is cute” or “this speaker has a strong feeling of responsibility”. While the anger level described above refers to an emotion of a speaker, the impression refers to an emotion of a receiver. For example, the calculation formula specifying unit 11Z may determine values obtained by digitizing various impressions of a speaker such as a core strength level, a cuteness level, an honesty level, a responsibility strength, and a crazy level, which are given to the receiver from the line based on texts included in the line. An algorithm for determining a value obtained by digitizing the impression is the same as the algorithm described above with reference to the anger level. Then, the calculation formula specifying unit 11Z specifies a calculation formula having a variable of a value obtained by digitizing the impression.

(Digitization of Topic Included in Line)

Content of a line may refer to, in a non-limiting manner, a topic (utterance target) included in the line. For example, when a keyword such as “Aristotle” and “Kant” is included in a line, it is very likely that a speaker talks about philosophy. When a keyword such as “soft and creamy rice omelet” is included in a line, it is very likely that a speaker talks about food. In this case, the calculation formula specifying unit 11Z can digitize the line with reference to “topic difficulty”. For example, the topic difficulty when a topic is food may be 1, and the topic difficulty when a topic is philosophy may be 5. An algorithm for determining a value obtained by digitizing a topic included in a line may be the same as that of the anger level as described above. Then, the calculation formula specifying unit 11Z specifies a calculation formula having a variable of a value obtained by digitizing a topic included in a line.

Alternatively, the calculation formula specifying unit 11Z may digitize content of a line based on various criteria. The calculation formula specifying unit 11Z specifies one or more calculation formulas based on a value obtained by digitizing the content of the line.

As described above, the calculation formula specifying unit 11Z specifies one or more calculation formulas based on a numerical value indicating content of a line combined with a bubble. Accordingly, the bubble creating unit 12Z can create a bubble having an appearance suitable for the content of the line combined with a bubble. Therefore, the interest of a player in a video game can be further improved.

FIG. 19 is a diagram showing a change of a bubble corresponding to a variable according to at least one of the embodiments of the present disclosure.

The calculation formula specifying unit 11Z specifies one or more calculation formulas based on the number of characters or words of a line combined with a bubble. Here, the term “line combined with a bubble” refers to a line that is displayed in a manner of overlapping a frame image when the frame image of the bubble is displayed on a game screen or the like.

For example, when content of a line is “We are looking for a legendary sword”, the number of words is 7 (the number of characters including space is 36). When content of a line is “In a cave located beyond the northern mountain, the legendary sword may be sleeping”, the number of words is 14 (the number of characters including space is 83). The calculation formula specifying unit 11Z specifies the calculation formula 002 having a variable 1 indicating “the number of characters or words of a line” with reference to FIG. 17 . In FIG. 19 , a bubble SB04A has an appearance of a bubble created by the bubble creating unit 12Z when the number of words is 7. A bubble SB04B has an appearance of a bubble created by the bubble creating unit 12Z when the number of words is 14. A bubble frame is enlarged in a vertical direction (a long axis direction of an ellipse) when the number of words are large.

As described above, the calculation formula specifying unit 11Z specifies one or more calculation formulas based on the number of characters or words of a line combined with a bubble. Accordingly, the bubble creating unit 12Z can create a bubble having an appearance suitable for the number of characters or words of a line combined with a bubble. Therefore, the interest of a player in a video game can be further improved.

FIGS. 20 and 21 are diagrams showing changes of bubbles corresponding to variables according to at least one of the embodiments of the present disclosure.

The calculation formula specifying unit 11Z specifies one or more calculation formulas based on a volume or voice quality of voice data corresponding to a line combined with a bubble. Here, the term “line combined with a bubble” refers to a line that is displayed in a manner of overlapping a frame image when the frame image of the bubble is displayed on a game screen or the like.

(Voice Data Corresponding to Line)

Voice data corresponding to a line refers to voice data reproduced together with a display when a bubble combined with a line is displayed. For example, in a video game or the like, voice data generated by a voice actor reading out a line may be reproduced together with a display of a bubble combined with the line. In a live video, a talk event, or the like, an utterance of a commentator or a performer is collected by a microphone and is recorded as voice data. The recorded voice data is reproduced together with a display of a bubble (such as a display in a live video and a display on a large screen in an event site or the like). The voice data is an example of data corresponding to a line.

The calculation formula specifying unit 11Z specifies a calculation formula having a variable indicating a volume of voice data corresponding to a line (hereinafter, simply referred to as a volume of a line). The calculation formula specifying unit 11Z specifies the calculation formula 009 having a variable 1 indicating “a volume of a line (1 to 20)” with reference to FIG. 17 . In FIG. 20 , a bubble SB05A has an appearance of a bubble created by the bubble creating unit 12Z when a volume of a line is 1. A bubble SB05B has an appearance of a bubble created by the bubble creating unit 12Z when a volume of a line is 18. When a voice of a speaker is loud, sizes of thorns provided at a bubble frame are large and a size of the bubble is large.

The calculation formula specifying unit 11Z specifies a calculation formula having a variable indicating voice quality of voice data corresponding to a line (hereinafter, simply referred to as voice quality of a line). Various criteria for digitizing voice quality can be considered, and breath leakage level of a voice actor is used here. A voice having a high breath leakage level (breathy voice) has a breath leakage level of 10 and a voice having a low breath leakage level has a breath leakage level of 1. An existing voice processing technique may be used for digitization (for example, calculation of a breath leakage level) based on voice data. The calculation formula specifying unit 11Z specifies the calculation formula 010 having a variable 1 indicating “voice quality of a line (breath leakage level of 1 to 10)” with reference to FIG. 17 . In FIG. 21 , a bubble SB06A has an appearance of a bubble created by the bubble creating unit 12Z when a breath leakage level is 1. A bubble SB06B has an appearance of a bubble created by the bubble creating unit 12Z when a breath leakage level is 5. A degree of blurring of an outer edge portion of the bubble SB06B is larger than that of the bubble SB06A. An amount of exhaled air in a voice is expressed as a degree of blurring of a bubble frame.

Voice quality of a line is not limited to the breath leakage level. For example, voice quality of a line includes a low voice of a speaker, a degree of an edged voice, a degree of a nasal voice, sound quality, tone, and the like. These types of voice quality of a line are digitized, and the calculation formula specifying unit 11Z specifies a calculation formula having a variable of digitized values.

As described above, the calculation formula specifying unit 11Z specifies one or more calculation formulas based on a volume or voice quality of voice data corresponding to a line combined with a bubble. Accordingly, the bubble creating unit 12Z can create a bubble having an appearance suitable for the volume or the voice quality of the voice data corresponding to a line. Therefore, the interest of a player in a video game can be further improved.

FIG. 22 is a diagram showing a change of a bubble corresponding to a variable according to at least one of the embodiments of the present disclosure.

The calculation formula specifying unit 11Z specifies one or more calculation formulas based on an attribute value of a speaker of a line combined with a bubble. Here, the term “line combined with a bubble” refers to a line that is displayed in a manner of overlapping a frame image when the frame image of the bubble is displayed on a game screen or the like.

(Attribute (Value) of Speaker)

An attribute of a speaker refers to a property of the speaker. An attribute value of the speaker refers to digitization of the attribute of the speaker. For example, examples of an attribute of a speaker include sex, age, physical strength, intelligence, charm, agility, arm strength, wisdom, bravery, luck, recovery power, hit point (HP), magic point (MP), physical attack resistance, magic attack resistance, and the like of a character who appears in a story or a game. The attribute of a speaker is not limited thereto. Hereinafter, a case where the attribute of a speaker is a hit point (HP) of a character who appears in a game will be described.

The calculation formula specifying unit 11Z specifies a calculation formula having a variable indicating a hit point (HP) of a speaker of a line. The calculation formula specifying unit 11Z specifies the calculation formula 001 having a variable 1 indicating an “HP of a character” with reference to FIG. 17 . In FIG. 22 , a bubble SB07A has an appearance of a bubble created by bubble creating unit 12Z when an HP of a character is fairly high. A bubble SB07B has an appearance of a bubble created by the bubble creating unit 12Z when an HP of a character is low. Although a basic shape of a bubble in the present example is an elliptical shape, the ellipse extends in a major axis direction and contracts in a minor axis direction corresponding to a reduction in an HP of a character. That is, a bubble frame is crushed to be thin corresponding to the reduction of the HP of the character. Accordingly, a state indicating the character is weak is expressed.

In addition, the calculation formula specifying unit 11Z may specify one or more calculation formulas based on various attribute values of a speaker.

As described above, the calculation formula specifying unit 11Z specifies one or more calculation formulas based on an attribute value of a speaker of a line combined with a bubble. Accordingly, the bubble creating unit 12Z can create a bubble having an appearance suitable for an attribute of a speaker of a line combined with a bubble. Therefore, the interest of a player in a video game can be further improved.

FIG. 23 is a diagram showing a change of a bubble corresponding to a variable according to at least one of the embodiments of the present disclosure.

The calculation formula specifying unit 11Z specifies one or more calculation formulas based on a numerical value indicating an environment in which a speaker of a line combined with a bubble is present. Here, the term “line combined with a bubble” refers to a line that is displayed in a manner of overlapping a frame image when the frame image of the bubble is displayed on a game screen or the like.

(Environment in Which Speaker is Present)

An environment in which a speaker is present refers to an environment around the speaker. For example, when the speaker is an in-game character that appears in a game, the environment in which the speaker is present includes the following environments such as a place where a character currently stays (a town, a village, a city, a dungeon, a cave, a shrine for recovering physical strength, a prairie, a mountain, sea, and the like), the number of partners or status of partners, whether a character encounters an enemy character, current time for a character (for example, morning, noon, sunset, night, midnight, and the like), weather (sunny, rain, heavy rain, snow, thunder, and the like), a group to which a character belongs, a combat stance of a group to which a character belongs (focus on a short-distance attack, focus on a long-range attach, focus on defense, focus on survival, and the like), a collection status of items that are essential for the progress of a game, remaining time until a character clears a given mission, security of a place where a character currently stays, whether villagers or towns-folks like or dislike a character, an era when a character is present (ancient, modern, modern, future, and the like), power distribution in a world where a character is present (demon king army dominates, humans dominate, and the like), an economic situation of a world where a character is present (boom, recession, famine, and the like), and a spreading situation of an infectious disease in a world where a character is present (no infectious disease, pandemic, epidemic, and the like).

When a speaker is a person present in the real world (for example, a game commentator, a participant of an event, or the like), an environment in which the speaker is present includes the following environments such as a place where a speaker currently stays (municipality, outdoor, indoor facility, and the like), the number of participants of speakers (the number of viewers watching a posted video, the number of participants of an event, and the like), an attribute of participants of speakers (classmates, work colleagues, first met, and the like), current time (for example, morning, noon, sunset, night, midnight, and the like), a traffic condition when a speaker moves (traffic jam, delay of train operation, and the like), weather near a place where a speaker currently stays or near home of the speaker (sunny, rain, heavy rain, snow, thunder, and the like), remaining time given to a speaker (remaining recording time of a video, time until the end of an event, and the like), security of a place where a speaker currently stays, an economic situation of an area where a speaker is present (boom, recession, and the like), and a spreading situation of an infectious disease in a world where a character is present (no infectious disease, pandemic, epidemic, and the like).

An environment where a speaker is present is not limited to the environments described above. Hereinafter, a case where an environment in which a speaker is present is a distance between an in-game character who is a speaker and an enemy character (a distance to the enemy character) will be described.

The calculation formula specifying unit 11Z specifies a calculation formula having a variable indicating a distance to an enemy character. The calculation formula specifying unit 11Z specifies the calculation formula 012 having a variable 1 indicating a “distance to an enemy character” with reference to FIG. 17 . In FIG. 23 , a bubble SB08A has an appearance of a bubble created by the bubble creating unit 12Z when a distance to an enemy character is fairly large. A bubble SB08B has an appearance of a bubble created by the bubble creating unit 12Z when a distance to an enemy character is reduced. A state in which an in-game character becomes tense because an enemy character is coming close is expressed as the number of thorns provided at a bubble frame.

As described above, the calculation formula specifying unit 11Z specifies one or more calculation formulas based on a numerical value indicating an environment in which a speaker of a line combined with a bubble is present. Accordingly, the bubble creating unit 12Z can create a bubble having an appearance suitable for the environment in which the speaker is present. Therefore, the interest of a player in a video game can be further improved.

FIG. 24 is a diagram showing a change of a bubble corresponding to a variable according to at least one of the embodiments of the present disclosure.

The calculation formula specifying unit 11Z specifies one or more calculation formulas based on the number of speakers of a line combined with a bubble. Here, the term “line combined with a bubble” refers to a line that is displayed in a manner of overlapping a frame image when the frame image of the bubble is displayed on a game screen or the like.

The calculation formula specifying unit 11Z specifies a calculation formula having a variable indicating the number of speakers of a line. The calculation formula specifying unit 11Z specifies the calculation formula 007 having a variable 1 indicating “the number of speakers of a line” with reference to FIG. 17 . In FIG. 24, a bubble SB09A has an appearance of a bubble created by the bubble creating unit 12Z when the number of speakers is one. A bubble SB09B has an appearance of a bubble created by the bubble creating unit 12Z when the number of speakers is three. At the same time, the number of speakers of a line is expressed as the number of bubble frames that are concentrically overlapped with one another.

As described above, the calculation formula specifying unit 11Z specifies one or more calculation formulas based on the number of speakers of a line combined with a bubble. Accordingly, the bubble creating unit 12Z can create a bubble having an appearance suitable for the number of speakers. Therefore, the interest of a player in a video game can be further improved.

FIG. 25 is a diagram showing a change of a bubble corresponding to a variable according to at least one of the embodiments of the present disclosure.

The calculation formula specifying unit 11Z specifies one or more calculation formulas based on an operating time of a video game. The operating time may be an operating time of a server that controls the progress of the game. The operating time may be a time (play time) from when a user (player) having a user terminal starts the game to current time. The operating time may be an elapsed time when a time point at which a predetermined event occurs in the game in progress is set to a time point 0.

The calculation formula specifying unit 11Z specifies a calculation formula having a variable indicating an operating time of a video game. The calculation formula specifying unit 11Z specifies the calculation formula 006 having a variable 1 indicating “an operating time of a game” with reference to FIG. 17 . In FIG. 25 , a bubble SB10A has an appearance of a bubble created by the bubble creating unit 12Z when an operating time of a video game is short. A bubble SB10B has an appearance of a bubble created by the bubble creating unit 12Z when an operating time of a video game is long.

Here, a utilization example of a bubble shown in FIG. 25 will be described. For example, among in-game characters (main character) operated by a player, there is a character who is an assistant (a sidekick character). The sidekick character is called from another world, is created by magic, or the like such that the sidekick character accompanies the main character. When a predetermined period of time is elapsed, the sidekick character leaves the main character because the sidekick character returns to the other world, the main character who is a caller is short of magic, and the like. A line of the sidekick character is displayed on a game screen together with an image of a bubble created by the bubble creating unit 12Z based on the calculation formula 006. For example, in such a case, when an operating time of a video game increases, a bubble becomes more transparent. Accordingly, it is possible to visually express a remaining time until a time limit at which the sidekick character leaves the main character. In addition, in a case where the main character is poisoned, a state in which the influence of the poison is diminished may be shown by a bubble created by the bubble creating unit 12Z based on the calculation formula 006.

The calculation formula specifying unit 11Z may specify a calculation formula such that a shape of a bubble changes when an operating time of a video game increases. For example, the calculation formula specifying unit 11Z specifies a calculation formula that defines a shape of which a basic shape is a rectangle without corners and becomes closer to a circle when an elapsed time increases. Accordingly, it is possible to present a situation in which personality of a young speaker who is an in-game character becomes gentle when the age increases.

As described above, the calculation formula specifying unit 11Z specifies one or more calculation formulas based on an operating time of a video game. Accordingly, the bubble creating unit 12Z can create a bubble having an appearance suitable for the operating time of the video game. Therefore, the interest of a player in a video game can be further improved.

FIG. 26 is a diagram showing a change of a bubble corresponding to a variable according to at least one of the embodiments of the present disclosure.

The calculation formula specifying unit 11Z specifies one or more calculation formulas based on a gazing position on a game screen of a player of a video game. Here, the gazing position on a game screen refers to a position on the game screen where the game player gazes. For example, when a cursor is displayed on a game screen such as a personal computer, a gazing position on a game screen may refer to a position of the cursor. When a game screen is displayed on a touch panel display, a gazing position on a game screen may refer to a position where a user (a player of a video game) taps the touch panel display. When a game screen is displayed on VR goggles having a gaze detection function, a gazing position on a game screen may refer to a position indicated by a line of sight of a person who wears the VR goggles.

The calculation formula specifying unit 11Z specifies a calculation formula having a variable indicating a gazing position on a game screen of a player of a video game. The calculation formula specifying unit 11Z specifies the calculation formula 011 having a variable 1 indicating “coordinate values (x, y) of a gazing position on a game screen” with reference to FIG. 17 . In FIG. 26 , a bubble SB11A has an appearance of a bubble created by the bubble creating unit 12Z when a gazing position is not located in a predetermined area of a game screen. A bubble SB11B has an appearance of a bubble created by the bubble creating unit 12Z when a gazing position is located in a predetermined area of a game screen. When a gazing position is located in a predetermined area of a game screen, thorns of a bubble frame are extended.

Here, a utilization example of a bubble shown in FIG. 26 will be described. A player of a video game experiences a game from the viewpoint of a main character A who is an in-game character. For example, another in-game character (for example, a partner B belonging to the same team with the main character A) who is featured on a game screen is speaking in the game, and a line of the partner B is displayed in combination with a bubble. The predetermined area of a game screen is an area where a bubble is displayed. At this time, a case where a gazing position is located in the predetermined area of the game screen is a case where the main character A (player) is looking at a bubble related to the utterance of the partner B. This corresponds to a case where the main character A (player) is listening to the utterance of the partner B. Therefore, it can be expressed that the partner B is aware of the fact that “the main character A (player) is listening to the utterance of the partner B” by extending thorns of a bubble frame.

Another utilization example of the bubble shown in FIG. 26 will be described. For example, a rare item that increases attack power of the main character A (player) is hidden somewhere on a game screen. The main character A (player) moves the line of sight (or moves a cursor or taps) to search for the rare item. Here, the main character A (player) can find a rare item only in a time zone in which the partner B reads an incantation of “search” with a gesture. Texts corresponding to the incantation read by the partner B are displayed in a bubble frame. When a gazing position of the main character A (player) overlaps a position where the rare item is hidden, thorns of the bubble frame are extended. Accordingly, the partner B reads the incantation with a gesture, and the partner B cannot give a hint regarding the position of the rare item to the main character A (player) using words or a gesture, but the partner B can express a situation in which a hint is given by some other methods such as a sign.

As described above, the calculation formula specifying unit 11Z specifies one or more calculation formulas based on a gazing position on a game screen of a player of a video game. Accordingly, the bubble creating unit 12Z can create a bubble having an appearance suitable for the gazing position on the game screen of the player. Therefore, the interest of a player in a video game can be further improved.

FIG. 27 is a diagram showing a change of a bubble corresponding to a variable according to at least one of the embodiments of the present disclosure.

The calculation formula specifying unit 11Z specifies one or more calculation formulas based on a numerical value indicating a user experience offered to a player of a video game.

(User Experience)

Here, a user experience (UX) is a generic term for an experience obtained through a product or a service. For a video game, a user experience refers to an experience obtained when a player plays the video game. For example, feelings of a player when the player plays a game correspond to a user experience, such as tension, calming down (relaxation), laughing, anger, satisfaction, and unsatisfaction. The user experience in a video game is not limited to those described above.

(Digitization of Tension Level)

“Tension” and “relaxation” that are examples of a user experience described above will be described. For example, a player in a game may be desired to get tense, for example, when a user starts to get bored in playing the game. On the other hand, when a state of tension continues, a player is likely to get tired, so that it is desired to relax the player. Therefore, a numerical index such as a tension level is introduced in order to maintain an appropriate tension level of a player. For example, when a player is not tense at all, the tension level is set to 0. When the player is extremely tense, the tension level is set to 10. Here, although a maximum value of the tension level is defined as 10, the maximum value of the tension level may be a value other than 10.

The calculation formula specifying unit 11Z specifies a calculation formula having a variable indicating a tension level. The calculation formula specifying unit 11Z specifies the calculation formula 013 having a variable 1 indicating “a tension level of a player” with reference to FIG. 17 . In FIG. 27 , a bubble SB12A has an appearance of a bubble created by the bubble creating unit 12Z when it is desired that a player is not tense (when it is desired to reduce a tension level of a player). A bubble SB12B has an appearance of a bubble created by the bubble creating unit 12Z when it is desired that a player is tense (when it is desired to increase a tension level of a player).

For example, a bubble created by the bubble creating unit 12Z based on the calculation formula 013 is used for a narration display in a game. In this case, a speaker of the narration is a game system. A stimulus given to a player by a narration display using the bubble SB12B having thorns is stronger than that by a narration display using the bubble SB12A having no thorns. Therefore, a player can become more tense by using the bubble SB12B having thorns. The calculation formula specifying unit 11Z may specify a calculation formula such that a color of a bubble comes close to red when a tension level desired to be given to a player is high. Since red is a color offering a strong visual stimulus, it is possible to make a player more tense.

User experiences other than “tension” and “relaxation” offered to a player may be digitized. The calculation formula specifying unit 11Z specifies a calculation formula having a variable indicating the digitized user experiences.

As described above, the calculation formula specifying unit 11Z specifies one or more calculation formulas based on a numerical value indicating a user experience offered to a player of a video game. Accordingly, the bubble creating unit 12Z can create a bubble having an appearance suitable for a user experience desired to be offered to a player of a video game. Therefore, the interest of a player in a video game can be further improved.

(Supplementary Items for Sixth Embodiment)

The calculation formula specifying unit 11Z may specify a calculation formula that does not have a variable (for example, the calculation formula 005 in FIG. 17 ). When an appearance of a bubble does not need to change, a predetermined fixed value may be input to a variable part of a calculation formula having a variable (for example, the calculation formulas 001 to 004 and 006 to 013 in FIG. 17 ). When a calculation formula includes two or more variables, a predetermined fixed value may be input to some of the variables.

An element to be considered (hereinafter referred to as a consideration element) in specifying a calculation formula may not be used as a variable included in a calculation formula. Non-limiting examples of the consideration element include content of a line combined with a bubble (see FIG. 18 ), the number of characters or words of a line combined with a bubble (see FIG. 19 ), a volume or voice quality of voice data corresponding to a line combined with a bubble (see FIGS. 20 and 21 ), an attribute of a speaker of a line combined with a bubble (see FIG. 22 ), an environment in which a speaker of a line combined with a bubble is present (see FIG. 23 ), the number of speakers of a line combined with a bubble (see FIG. 24 ), an operating time of a video game (see FIG. 25 ), a gazing position on a game screen of a player of a video game (see FIG. 26 ), and a user experience offered to a player of a video game (see FIG. 27 ).

The consideration elements may not be digitized. More specifically, the content of a line combined with a bubble that is a consideration element (see FIG. 18 ), the voice quality of voice data corresponding to a line (see FIG. 21 ), the attribute of a speaker (see FIG. 22 ), the environment in which a speaker of a line is present (see FIG. 23 ), and the user experience offered to a player of a video game (see FIG. 27 ) may not be digitized when a calculation formula is specified. For example, a calculation formula to be specified by the calculation formula specifying unit 11Z may be determined in advance based on various conditions obtained from the consideration elements described above, for example, a calculation formula N may be used when a predetermined keyword is included in a line, a calculation formula N+1 may be used when the number of characters or words of a line is less than 20, a calculation formula N+2 may be used when the number of characters or words of a line is 20 or more, and a calculation formula N+3 may be used when a user experience offered to a player of a video game is “it is desired to make a player laugh”. For example, in such a case, a consideration element that is not digitized can be used as a determination criterion (a criterion for selecting a calculation formula) for specifying a calculation formula.

When a calculation formula is specified, a plurality of consideration elements may be used in combination. Here, the calculation formula specifying unit 11Z specifies the calculation formula 004 having a variable 1 indicating “a bravery level of a character (1 to 255)” and a variable 2 indicating “a distance to an enemy character” with reference to FIG. 17 . The “bravery level of a character” corresponds to an attribute of a speaker (see FIG. 22 ), and the “distance to an enemy character” corresponds to an environment in which a speaker of a line is present (see FIG. 23 ). As described above, various consideration elements are classified into a plurality of categories (see FIGS. 18 to 27 ), and the consideration elements are divided and described for each category. Alternatively, the calculation formula specifying unit 11Z may specify a calculation formula in consideration of consideration elements included in different categories. When the calculation formula specifying unit 11Z specifies the calculation formula 004, the bubble creating unit 12Z creates a bubble having a circular basic shape. Expansion to contraction of the created circular bubble is repeated at a predetermined cycle. An animation display expresses a heartbeat of a character who is about to encounter an enemy character. When a distance to an enemy character becomes short, a speed at which a radius of the circle changes increases, and thus the heart beat becomes faster. A brave character can calmly deal with an enemy character while a non-brave character is scared when the non-brave character encounters an enemy character. Therefore, an amplitude of a radius of the circle increases when a bravery level becomes low. That is, the heart beat becomes faster. The calculation formula 004 expresses a mood of a character using the created bubble.

In order to specify a speaker, a tail may be added to a bubble. The tail added to a bubble may be referred to as “foot”, “number”, “arrow”, “pointy part”, or “notch”. Here, a portion added to a bubble in order to specify a speaker is expressed as a “tail”. A shape of a tail is not limited to a triangle (see FIG. 28 ), and can be various shapes. For example, the tail may have a bent shape. There is also a “round tail” or the like formed by continuously arranging a plurality of circles. Hereinafter, an example of a generally used triangular tail will be described.

FIG. 28 is a diagram showing a bubble added with a tail according to at least one of the embodiments of the present disclosure. A triangular tail T is added to a bubble SB13. The calculation formula specifying unit 11Z may specify a calculation formula that defines an appearance of the bubble SB13 and a calculation formula that defines an appearance of the tail T. The bubble creating unit 12Z creates the bubble SB13 added with the tail T by using the calculation formula that defines the appearance of the bubble SB13 and the calculation formula that defines the appearance of the tail T.

It is considered that the number of patterns of a shape available for the tail T is smaller than the number of patterns of a shape available for the bubble SB13. Therefore, an image that is an asset (material) of the tail T may be stored in a storage unit (a storage medium or storage device), and the tail T may be added to the created bubble SB13 later.
